Abstract: A compact, tunable, wavelength independent, all-fiber attenuator is produced by heating a single-mode fiber to create at  least one taper therein through capillarity rather than through pulling, pushing or twisting the fiber.          The attenuator may be tuned to achieve the desired value of attenuation and wavelength independence by imparting a small bend to the taper. The attenuator may be a fixed value attenuator or a variable attenuator. When a fixed value attenuator is desired, the tapered and bent structure is encapsulated in an adhesive and glued onto a substrate.

Abstract: L'invention concerne une nouvelle kinase lipidique appartenant à la famille des kinases P13. Les kinases P13 catalysent l'addition de phosphate à l'inositol produisant un monophosphate, un diphosphate et un triphosphate d'inositol. Les phosphates d'inositol ont une incidence dans la régulation de cascades de signalement intracellulaires qui entraîne des modifications d'expression génique, lesquelles, entre autres effets, peuvent causer un remodelage de la cytosquelette et une modification de la motilité cellulaire. Plus particulièerment, l'invention concerne une nouvelle kinase humaine de la famille P13, la kinase p110 delta , qui interagit avec la kinase p85, a une large spécificité phosphoinositidique et est sensible aux mêmes inhibiteurs que la kinase p110 delta  de la famille P13. Toutefois, à la différence des kinases P13. Toutefois, à la différence des kinases P13 précédemment identifiées qui ont un mode d'expression ubiquiste, la kinase p110 delta  s'exprime sélectivement dans les leucocytes. Qui plus est, la kinase p110 delta  révèle une expression étendue dans la plupart des mélanomes attestés, et peut donc jouer un rôle crucial dans la régulation de la faculté métastatique révélée par des mélanomes. L'identification d'agents qui augmentent ou réduisent l'activité de la kinase p110 delta  peut ainsi empêcher la métastase cancéreuse.

Title: Method for detecting cell proliferative disorders
Inventor: SIDRANSKY DAVID
IPC: C12Q1/6883
Filed: 1997-08-28
Granted: 2006-12-12
Abstract: The present invention relates to the detection of a cell proliferative disorder associated with alterations of microsatellite DNA in a sample. The microsatellite DNA can be contained within any of a variety of samples, such as urine, sputum, bile, stool, cervical tissue, saliva, tears or cerebral spinal fluid. The invention is a method to detect an allelic imbalance by assaying microsatellite DNA. Allelic imbalance is detected by observing an abnormality in an allele, such as an increase or decrease in microsatellite DNA which is at or corresponds to an allele. An increase can be detected as the appearance of a new allele. In practicing the invention, DNA amplification methods, particularly polymerase chain reactions, are useful for amplifying the DNA. DNA analysis methods can be used to detect such a decrease or increase. The invention is also a method to detect genetic instability of microsatellite DNA. Genetic instability is detected by observing an amplification or deletion of the small, tandem repeat DNA  sequences in the microsatellite DNA which is at or corresponds to an allele. The invention is also a kit for practicing these methods.
